Method for noise creation in internal combustion engine entails setting exhaust gas return valve in oscillation at such frequency that induction noise inside induction line is influenced

The method is for noise creation in an internal combustion engine which entails controlling by a return valve the volume of exhaust gas which is returned to the induction line. The exhaust gas return valve (10) in its at least partially opened position is set in oscillation at such a frequency that...

Beschreibung
Zusammenfassung:The method is for noise creation in an internal combustion engine which entails controlling by a return valve the volume of exhaust gas which is returned to the induction line. The exhaust gas return valve (10) in its at least partially opened position is set in oscillation at such a frequency that the induction noise inside the induction line (3) is influenced. The exhaust gas return valve is controlled by a control device (11) which is supplied by an accelerator nominal value (12) and operating data (13) of the internal combustion engine and/or motor vehicle. Bei einem Verfahren zur Geräuschgestaltung bei einer Brennkraftmaschine (1) werden über eine Abgasrückführleitung (8) in der Brennkraftmaschine (1) erzeugte Abgase einer zu der Brennkraftmaschine (1) führenden Ansaugleitung (3) zugeführt und die in die Ansaugleitung (3) rückgeführte Abgasmenge wird durch ein Abgasrückführventil (10) gesteuert. Das Abgasrückführventil (10) wird in seiner zumindest teilweise geöffneten Stellung mit einer derartigen Frequenz in Schwingungen versetzt, dass das Ansauggeräusch innerhalb der Ansaugleitung (3) beeinflusst wird.
